Disclosed are systems and methods for treating contaminated material. The material is heated by nonconductive and nonconvective heating in a vacuum chamber such that the surface of the material is heated without significant heating of the air within the chamber. The surface of the material is heated to at least a volatilization temperature of the contaminants or to a decomposition temperature of one or more compounds in intimate contact with the contaminants, so that the concentration of contaminants in the material is reduced. Exhaust is removed from the chamber and cooled. A solids and/or liquids collector removes condensed solids and/or liquids and has a gas outlet connected to a vacuum pump.

Systems and methods for treating contaminated solid material

A system can include a multi-material fluid having a mixture of a first material and a second material. The system can also include a first vessel into which the multi-material fluid is disposed. The system can further include a first sonication device disposed, at least in part, in the multi-material fluid in the first vessel. The first sonication device, when operating, can emit ultrasound waves into the multi-material fluid. The ultrasound waves separate the first material and the second material from each other in the first vessel.
